Re: 408 Cheytac vs. 50 Cal

I am not offended and I apologize if I came off as being cranky. You made a statement and I would like to see the numbers you used to arrive at your conclusions, you may know something I don't. You really need to have the facts when discussing ballistics on this site. This place is full of people that will take you to school for posting BS.

All things considered the 375 comes out on top for civilian uses. Military applications is a whole different ball game.

Oh, who is shooting 7 miles with a 50?

Im shooting a AR-50 right now and working on gettting a 375 or 408. Guys have me on one side of 408 for availability and costs to shoot others have me on side of 375 for hands down accuracy and range. I want to shoot "soft points" for hunting and using A-maxs now. Found Rocky Mountain Bullet company for "soft points" in 408 and 375. I can't get them to group in my AR-50 like i can with my A-maxes. I need to work on my loads some more - have older ar-50 with bolt for bolt release. Can't even measure to lands cause bullet falls out of case before touches. Newer ones I guess aren't so bad and want to get my hands on National Match.

That is all besides the point.

What is your opinion on 375 vs 408. Will help this thread and me.

MEANT 408 instead of 406

Re: 408 Cheytac vs. 50 Cal

I have no knowledge of a 406, do mean 408? I have shot the 375 quite a bit and I really like it. Sierra is making the 350 SMK again and Berger is supposed to have some of the hybrids in 375 in the pipeline. I don't have any experience with the 408 but it is probably a matter of choice as to which is more suitable.

Re: 408 Cheytac vs. 50 Cal

why not the 375 chey-tac. 1 sec on target at 1000yd, blazing speed, lower recoil. think the 375 was for fleshy targets, the 408 for barrier/vehicle if I am correct

midway had the brass and bullets but now, like all else, temp unavailable. know it wasn't the 408 or 50 cal but would be my preference unless you have other plans. just throwing that out.

anyways, new to forum sign up, been a long time reader

Re: 408 Cheytac vs. 50 Cal

I know this is an old post, but I still gotta laugh at the whole "7 miles" comment.

Acording to the sierra I6 program, a .510 AMAX fired at 2750 fps at 0 elevation at 58 degrees F has a MAXIMUM range of 5.27 miles when fired at a 34 degree angle.

So...BS on the whole 7 mile deal!!

Re: 408 Cheytac vs. 50 Cal

I'll throw this out there and you can take it or leave it. All I've got are a few experiences with different ELR cartridges while out shooting with friends. Also some of these comments are from other friends about experiences with their friends with their rifle's and ELR cartridges.

375CT on 2.5 moa steel at 2500Y. Easy to hit in mild conditions of 1-4 MPH winds. Both a friend and I were shooting and near as we could tell the groups were less than 2'. We also shot at 2000Y and didn't repaint the plate. 2000Y was no challenge at all.

Myself and K... 50 BMG/EDM windrunner/750amax at 2600fps/1moa capable. VS 375CT/Lawton 8000/Hooker 350 grain at 3150 fps. Engaging 2moa steel plates;

We were shooting side by side in the same conditions. Pretty even hitting plates until we got to 1900Y when the extra wind drift of the 50 made it hard to hit the plate. The 2050Y plate wasn't ever hit by the 50 even after 20 rounds. 3 shots in a row for the 375CT and 3 shot group of 7"s on the upper right side of the plate.

Hearsay...Friend J reported not being able to tell the difference in wind drift between his 338L/300 Berger hybrids and friends 408/419 solids. He reported his friend was having trouble staying less than MOA with the 408. 338L was more accurate and easier to hit with even out to 2200Y.

375CT, 338L, 300WM, 30-375R. Past 1 mile the 375CT was much easier to hit with in the wind. The BC of 1.1 G1 and the extra velocity made it a much more capable ELR cartridge past a mile.

The problem I had with the 375CT was excessive copper fouling with the Hooker 350's. After 40 rounds accuracy dropped off. The other thing I didn't like were the tiny dime sized copper colored splats on steel. Half the time I couldn't tell where on the steel I was hitting so I was unsure how to correct on the next shot for center hit.

When Berger comes out with a ELR .375 bullet I might revisit 375CT once again.

The 375 Cheytac does sound very interesting. Glad to see the write up. Thanks
